Vereinfache

\frac{- ln ( 1 + 6 x )}{x} : - \frac{ln ( 1 + 6 x )}{x}

= \frac{d}{d x} (- \frac{ln ( 1 + 6 x )}{x})

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= - \frac{\frac{d}{d x} ( ln ( 1 + 6 x ) ) x - \frac{d x}{d x} ln ( 1 + 6 x )}{x ^{2}}

\frac{d}{d x} (ln (1 + 6 x)) = \frac{6}{1 + 6 x}

\frac{d x}{d x} = 1

= - \frac{\frac{6}{1 + 6 x} x - 1 \cdot ln ( 1 + 6 x )}{x ^{2}}

Vereinfache

- \frac{\frac{6}{1 + 6 x} x - 1 \cdot ln ( 1 + 6 x )}{x ^{2}} : - \frac{6 x - ln ( 1 + 6 x ) ( 1 + 6 x )}{x ^{2} ( 1 + 6 x )}

= - \frac{6 x - ln ( 1 + 6 x ) ( 1 + 6 x )}{x ^{2} ( 1 + 6 x )}
